Testing of Nightly builds is a very important QA task and helps us track down regression bugs early.
This is essential to ensuring quality releases of Firefox and Firefox Mobile and we are very thankful for your work (testing, filing bugs, checking regression ranges). Our Firefox Community rocks!
To assist you better with Mobile nightly build testing and to inform you about current focus areas where Mozilla QA is working on (for example important landings of current features) we have created a new mailing lists especially for Mobile User of our Firefox Mobile Nightly Builds:
